A salty symphony: unraveling the tale of uromodulin and sodium sensitivity
摘要
Uromodulin is a kidney-specific glycoprotein which is uniquely synthesized by the epithelial cells lining the thick ascending limb and early distal convoluted tubule. Among multiple roles in complex physiological and pathological processes, uromodulin mediates renal sodium handling through modulating tubular sodium transporters that reabsorb sodium and therefore is putatively linked to hypertension through generating sodium sensitivity of blood pressure. This review aims to present an updated overview of the role of uromodulin in sodium renal handling and summarize the existing evidence originating from preclinical, genetic, and clinical studies that support a relationship between uromodulin and sodium-sensitive hypertension.
